Problem with USB enumeration on K60 board

MWMinor — Sat, 24 Jan 2015 22:05:35 GMT

Hi there

I have been having some problems with getting the USB port on my custom K60-based board, enumerating over VSB. Using the example virtual-com port as a starting point, I connected the USB to a laptop running Windows 7 and the laptop identifies the "device" as a HID - not a COM port. I have tried a different laptop, but the response is the same. I compiled the example and loaded it onto a TWRK60D100 board. The results were the same again.

Has anyone else had similar problems....??

Thanks

Ken

Hello Ken:

Can you point me to the specific demo you are using?

If this demo application belongs to the USB stack please provide a couple details.

- USB stack version.

- IDE.

- Path to the specific demo.

Hello Jorge

Many thanks for getting back to me and apologies for the delay in responding to your answer....

I found the root cause of the problem I was experiencing being a file that I had somehow included in the build - usb_init.c - which included the setup for a USB_HID. Once this was removed, the problem went away.

I appreciate your responding though.....

Regards

Ken
